I feel your pain and then some. Three that come to mind for me are the Bath Road from Bishop Sutton to West Harptree. There’s a little rise before Harptree and it mashes me every single time. Normally into a headwind. I go from mid group to solo ride in seconds. Secondly, I hate is as you approach Yatton after doing the moor from Clevedon - why does that bend into Yatton feel so sluggish?! Lastly, Clevedon Road between the bottom of Belmont and the double mini roundabout at the top of Long Ashton. I try to push to keep up but then the whole lug to Winford is a struggle.
Nice piece, John. Thanks for posting.
